Blood in stool?

Ivermetin was too strong for that young of a pup, but besides that is the pup able to drink on its own? If so treat it's water with some form of electrolyte, and antibotic, powder form from feedstore. If not able to drink consult with Wolf Creek Ranch.net they will have step by step instructions to keep pup hydrated and natural organic meds. to give the pup to help heal digestive tract to enable to eat own it's own and recipes for high protien diet to help heal digestive tract. Believe me this works i've tried it saved four pups, where others had dianosis from vet give shots/meds. and lost 4 pups. You can get the meds. from WCR in two days ordered/pay/delivered, meantime keep hydrated.
